How should you overtake a vessel in a narrow channel or fairway?

Overtaking a vessel in a narrow channel or fairway requires careful consideration of safety and navigation rules. The correct choice emphasizes that overtaking should only be conducted if it is safe and will not impede the passage of other vessels.

In narrow channels, the risk of collisions is heightened due to limited space and the potential presence of other vessels, so it is crucial to assess the situation before proceeding. This means evaluating the speed, direction, and proximity of not only the vessel being overtaken but also any other vessels that may be navigating in the channel. Ensuring that the maneuver does not obstruct or endanger other vessels maintains navigational safety and adheres to the principles set out in the COLREGs (International Regulations for Preventing Collisions at Sea).

When overtaking, it is also important to consider the rules of the road and if the action is necessary given the conditions at hand, ensuring that the maneuver is executed in a manner that does not compromise safety for any vessel involved.
